Boiler Replacement & Installation in Southeastern Wisconsin

Need a New Boiler? Replace What Needs Replacing. Keep What Still Makes Sense.

A good boiler replacement starts with understanding the heating system you already have.

Sometimes the boiler itself is the problem and the existing pumps, controls, zones and piping are worth keeping. Other homes need more than a box swap.

We look at the whole hydronic system, explain what can stay, what should change and why, then help you choose the replacement that makes sense for your home.

When Does Replacing a Boiler Make Sense?

We work on a lot of old boilers, and age by itself is not enough reason to replace one.

A boiler replacement starts making sense when the condition of the equipment, the repair in front of you or what you want from the heating system changes the economics.

The Boiler Itself Is Failing

An internal leak, failed heat exchanger or another major failure can make continued repair difficult to justify.

At that point, the question is no longer whether someone can get it running again. It is whether putting that money into the existing boiler still makes sense.

Important Parts Are Becoming Difficult or Impossible to Get

We still repair plenty of older boilers.

The decision changes when the part needed to make the repair is obsolete, unavailable or becoming increasingly difficult to support.

Several boiler replacements in our own service history started with exactly that problem.

You’re Stacking Expensive Repairs on Top of Each Other

One repair does not make a boiler bad.

Repeated major repairs are different.

When pumps, controls, combustion components or other expensive parts start piling up, it is reasonable to compare the cost of continuing down that road with putting the money toward a new boiler.

The Boiler Can No Longer Keep Up With the House

We see older systems that still run but struggle to maintain the temperature the homeowner is asking for, especially during colder weather.

Sometimes the problem can be repaired elsewhere in the hydronic system.

When the boiler itself is the limiting factor, replacement becomes a reasonable option.

You Want to Modernize More Than the Boiler

Some homeowners are ready to address aging controls, pumps, zoning, domestic hot water or an older mechanical-room layout at the same time.

That does not mean every old component automatically needs to go.

It means we can look at the system as a whole and show you what makes sense to do while it is already apart.

If your boiler can be responsibly repaired and that is the better decision, we’ll tell you.

If replacement deserves a serious look, we’ll explain why and help you understand what you are actually buying. 

How Much Does Boiler Replacement Cost?


The first question is how much of the heating system actually needs to be replaced.

If You Only Need the Boiler

If the boiler itself needs to be updated and the new boiler can be properly retrofitted into the existing pumps, controls, zones and piping, a straightforward conventional boiler replacement can often be completed for roughly $8,000 to $11,000, depending on the size of the boiler and equipment required.

That is the important starting point.

You do not automatically need to replace the entire hydronic heating system because you need a new boiler.

A Boiler Replacement Can Have Three Different Parts

A hydronic heating system is easier to understand when you break the project into three pieces.

1. The Boiler

The boiler is the equipment that heats the water used to warm the house.

Sometimes this is the only major part of the system that needs to change.

If the rest of the hydronic system is in good condition and compatible with the new boiler, we can keep the project focused on replacing the equipment instead of rebuilding things that are still doing their job.

2. The Controls & Circulation

This is everything responsible for telling the heat where to go and moving it through the house.

Depending on the system, that can include circulator pumps, zone valves, zone controls, thermostats, expansion tanks, fill components and air elimination.

Some homeowners opt to update aging pumps or controls while the boiler is already being replaced.

In other homes, those components are worth keeping.

New boiler does not automatically mean everything connected to it needs to be new.

3. The Piping & Heat Distribution

The boiler can make the heat. The piping still has to get it where it belongs.

That may mean radiators, hot-water baseboard, radiant floors or in-floor heating.

Some existing piping systems can be connected to a replacement boiler with relatively little change.

Other mechanical rooms have been modified several times over the decades and benefit from some repiping so the new boiler can operate, circulate and be serviced properly.

The boiler is one piece. The job is making the whole heating system work together.

Three Common Boiler-Replacement Scopes

Boiler-Only Retrofit

The existing pumps, controls, zoning and piping are serviceable and compatible with the new boiler.

We replace the boiler and the normal near-boiler components required for the installation, reconnect it to the existing system, commission it and put the heating system back into operation.

This is the simplest version of a boiler replacement.

Boiler + Controls or Circulation

The boiler needs replacement, and it also makes sense to address aging pumps, zone valves, controls, thermostats or other hydronic components while the system is apart.

Maybe something is already failing. Maybe the existing control does not work properly with the new equipment. Or maybe you would rather update a 25-year-old pump now than design the new system around it.

Those choices should be clear on the proposal so you know what each one adds and why.

Boiler + Hydronic System Upgrades

Some older systems need more work around the boiler.

That can include near-boiler piping, circulation changes, air elimination, zoning, old valves, indirect water heating or adapting an older distribution system to newer equipment.

At that point, you are investing in more than a boiler.

You are improving the heating system the boiler has to operate inside.

Why Can Two Boiler Quotes Be So Different?

Because they may not include the same project.

An $8,000–$11,000 boiler retrofit and a boiler project that includes high-efficiency equipment, multiple pumps, new zone controls, an indirect water heater or significant repiping are not two prices for the same work.

One is primarily an equipment replacement.

The other is a larger hydronic-system project.

That distinction matters when you compare proposals.

We Price the System You Actually Have

We look at the boiler, controls, circulation and piping before building the replacement scope.

If your existing pumps, controls and piping are worth keeping, we’ll tell you.

If something makes sense to update while the system is apart, we’ll explain what it is, why we recommend it and what it adds to the project.

Then you decide.

Which Boiler Should You Put Back In?


There is not one boiler that is automatically right for every house.

Standard efficiency, high efficiency, combi systems and indirect water heating can all make sense in the right application.

The better question is which setup works with the home you already have and gives you the ownership experience you actually want.

Standard-Efficiency Boilers

A conventional boiler can still be a very good answer.

These systems are familiar, relatively straightforward and can be a good fit when the existing venting and hydronic system lend themselves to a simpler replacement.

They also tend to keep the initial project smaller than a more involved high-efficiency conversion.

There is nothing wrong with choosing the simpler boiler when the simpler boiler fits the house.

High-Efficiency Condensing Boilers

High-efficiency boilers can be an excellent fit, but installing one can involve more than hanging a different box on the wall.

The system may require different intake and exhaust venting, condensate drainage, controls, circulation or piping.

That is part of why a high-efficiency replacement can cost considerably more than a straightforward conventional-boiler retrofit.

We look at the entire application before telling you whether the additional investment makes sense.

Higher efficiency is a choice. It should not be an automatic upsell.

Combi Boilers

A combi boiler handles space heating and domestic hot water in one appliance.

That can make a lot of sense in the right home.

Hot-water demand is important, though. A combi system is better suited to homes where the domestic hot-water demand is moderate.

If your household routinely needs a lot of hot water at the same time, a separate boiler with an indirect water heater may be the better setup.

We would rather size that decision around how your family actually uses hot water than sell the idea of one box simply because it sounds efficient.

Boiler + Indirect Water Heater

An indirect water heater stores domestic hot water in a separate tank and uses the boiler as the heat source.

For homes with larger hot-water demands, this can be a very strong setup.

It adds equipment and cost to the project, but it also allows the boiler and domestic-hot-water system to be designed around the actual demands of the home.

What Brand Boiler Does Austin Install?

We are selective about the boilers we choose to install.

The exact lineup can change as products, support and availability change. The standard does not.

We want equipment we would be comfortable putting in our own homes: reliable, serviceable, properly supported and worth owning long after installation day.

A more expensive boiler is not automatically a better boiler.

The best equipment is the equipment that fits the application and that we are comfortable standing behind.

Why Austin for Boiler Replacement?


Boiler replacement sits at the intersection of heating, plumbing, controls and sometimes electrical work.

That is why the company doing the job matters just as much as the boiler being installed.

1

We Understand the Whole Hydronic System
A boiler does not heat your house by itself.
Pumps, controls, zone valves, thermostats and piping still have to move that heat through the building. Boiler and hydronic heating work is a major part of what our team does, so the replacement is designed around the complete heating system rather than treating everything outside the boiler cabinet as somebody else’s problem.

2

A Tradesperson Helps You Make the Decision
The person looking at your boiler understands heating systems, replacement scope, controls, piping and what the installation is actually going to require. That matters when the right answer might be to replace less, reuse something you already own or choose a simpler piece of equipment. Our tradespeople are paid to solve the problem and recommend what makes sense for your home.

3

The Installation Follows Written Austin Standards
Code matters. It is the starting point. We also maintain written Austin Way installation standards covering the workmanship, safety, durability, serviceability and finish we expect from our own work. Every boiler replacement is permitted. The parts of the installation you cannot easily judge should still be done with the same care as the parts you can see.

4

Plumbing, Heating & Electrical Capability Under One Roof
Boiler projects cross trade lines more often than most HVAC installations. There is heating equipment and combustion. There is also piping, pumps, valves, controls and sometimes electrical work. Austin has those capabilities inside one organization. When the project crosses systems, you do not have to coordinate several companies yourself.

5

We Think About the Next Service Call While We Install It
A boiler should not only work on installation day.
It should be laid out so someone can properly maintain it, diagnose it and repair it years later. Clearances, piping layout, valves, controls and access all matter. Serviceability is part of craftsmanship.

6

The Company Behind the Boiler Is Built to Stay
Austin has served Southeastern Wisconsin since 1939. We remain privately owned and are building the company for perpetuity, not around an eventual sale. When you invest in a heating system that should be in your home for years, it matters who intends to be standing behind the work later.

What Happens When Austin Replaces Your Boiler?


A good boiler installation starts before anyone removes the old one.

1. You Know What Actually Needs to Change.

We look at the existing furnace and the home, then talk about what you want from the next system.

Comfort, reliability, efficiency, budget and how long you expect to own the home all matter.

If repairing the furnace you already own still makes more sense, we’ll tell you.

2. You Get Choices That Fit the House.

Standard efficiency or high efficiency.

Reuse existing controls or update them.

Keep the current hot-water setup, move to an indirect tank or consider a combi system.

We lay out the reasonable options and explain what changes with each one.

3. You Know the Scope and Price Before Installation Day.

Once you choose the system, you get the project scope and price before the work begins.

We also explain the applicable manufacturer warranty and Austin labor warranty for the equipment and scope you choose.

If financing helps make the project easier to manage, we can walk you through the available financing options for qualifying work.

4. The Job Is Prepared Before the Crew Gets There.

Boiler work takes equipment, valves, fittings, controls and a lot of material that varies from one house to the next.

We stage the equipment and materials for the installation and handle the permitting before the job gets underway.

A good installation day starts with the work that happened before the truck pulled into your driveway.

5. The Installation Takes the Time the System Requires.

Some straightforward boiler replacements can be completed in a day.

Larger hydronic projects may take multiple days when the scope includes piping, controls, zoning or domestic-hot-water work.

We work efficiently, but faster does not get to become rushed.

Your home is protected while we work, and the old equipment is removed as part of the project.

6. The Whole Heating System Gets Put Back Into Operation.

Installing the boiler is not the last step.

We fill and purge the system as required, set up the boiler, cycle the heating zones and verify the equipment and controls involved in the project.

If the boiler also serves an indirect water heater or domestic-hot-water system, that portion is checked as part of the startup.

Before we leave, you should know how the new system works and what was changed.

A boiler replacement is finished when the heating system is operating the way it should, not when the new boiler is merely hanging on the wall.

    Boiler Replacement Questions Homeowners Are Asking


    Who installs and replaces boilers near me?

    We do.

    Austin replaces and installs residential boilers throughout Southeastern Wisconsin, including Lake Country, Waukesha County, Washington County, Milwaukee and Ozaukee County.

    We work with conventional boilers, high-efficiency boilers and complete hydronic heating systems.

    That last part matters. A boiler installation can involve pumps, controls, zoning and piping in addition to the boiler itself, and those systems are a regular part of our heating work.

    Should I call a plumber or an HVAC company to replace a boiler?

    Call Austin.

    Boiler work crosses both trades.

    The equipment involves combustion, venting, electrical controls and heating-system setup. The hydronic side involves water, circulator pumps, valves, pressure and piping.

    Austin has plumbing and heating expertise under one roof, so we can deal with the boiler and the system it has to operate inside.

    You do not have to decide which trade owns the project before calling.

    Do I have to replace the whole heating system when I replace my boiler?

    No.

    If the existing pumps, controls, zoning, radiators, baseboard and piping are in good condition and compatible with the new boiler, much of the existing hydronic system can often stay.

    That is one of the first things we evaluate.

    A new boiler should be connected to a system that is worth keeping, not used as an excuse to replace good equipment that still has a job to do.

    Do you replace gas boilers?

    Yes.

    We replace residential gas-fired boilers, including conventional and high-efficiency equipment.

    The replacement can be a relatively straightforward retrofit when the existing system works with the new boiler, or a larger project when venting, controls, circulation or piping also need to change.

    We determine that scope before installation so you know what is actually included.

    Can you replace a boiler connected to radiant or in-floor heat?

    Yes.

    We replace boilers serving radiant floors, in-floor heating, hot-water baseboard, radiators and multi-zone hydronic systems.

    Those projects are exactly why boiler experience has to go beyond the appliance itself.

    The new boiler has to work with the water temperatures, pumps, zoning, controls and piping responsible for getting heat through the house.

    Boilers and complete hydronic heating systems are a major part of what we do.

    Should I repair my old boiler or replace it?

    Start with what failed.

    An old boiler can still be a good boiler.

    If the failure can be reasonably repaired, parts are available and the rest of the equipment is still worth owning, repairing it may make complete sense.

    Replacement deserves a serious comparison when the boiler has an internal failure, important parts are unavailable, major repairs are stacking up or another large repair is difficult to justify against the condition of the equipment.

    If we think replacement deserves consideration, we’ll explain why.
